(01. 83-28 'The present invention relates to new and useful improvements in grain treating machines and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character comprising novel means for thoroughly mixing dust with the grain.

Another very important object of the invention is to provide a machine of the aforementioned character wherein the force of the grain, flowing by gravity from a hopper, is utilized to actuate the mixing mechanism.

Still another very important object of the invention is to provide a grain treating machine of the character described embodying novel adjusting means/wherein the volume of dust which is mixed with the grain may be conveniently regulated as desired.

parent from a study of the following specifica-.

tion, taken in connection with the accompanying drawings wherein. like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a'view in side elevation of a grain treating machine constructed in accordance with the present invention, showing portions broken away in section.

Figure 2 is a view in front elevation of the machine.

Figure 3 is a cross sectional view through the rotary drum.

Figure 4 is a view in vertical longitudinal sec-- designated generally by the reference numeral I The frame structure I includes vertical legs 2, side braces or bars 3, end bars 4, etc. Mounted on the upper portion of the frame structure I is a hopper 5 for the reception of the grain to be treated. A manually adjustable slide 6 regulates the dust therein is had through the flow of the grain through the discharge' opening 1 of the hopper 5.

Journaled in suitable bearings 8 on the member 3 of the frame structure I is a shaft 9. Mounted on the shaft 9 for rotation beneath the'hopper 5 -5 is a drum for thereception of dust which is designated generally by .the reference numeral l 0. Access to the interior of the drum III for placing a suitable closure ll. .1 The drum in includes a pair of discs I2 which I are mounted on the shaft 9. Mounted on the peripheries of the discs l2 are-inner and outer rings [3 and M, respectively. The rings [3 and M are rotatably adjustable relative to each other 15 and said rings have formed therein communicating ports l5 and I6 for the discharge of the dust from the drum. It will be noted that the ports l5 and I6 are arranged in transverse series at circumferentially stated points in the rings I3 20 and I4.

Y -Fixed in the inner ring 13 are bolts 11. The bolts H are operable in circumferentially extending slots I8 which are provided therefor in the outer ring l4. Wing nuts 19 are provided on 25 the bolts ll for securing the inner ring l3, in adjusted position relative to the outer ring 14.

Adjustably mounted on the periphery of the drum Ill over the portsl5 and iii are grain buckets or cups 20. The buckets 20 include side so flanges 2| which are pivotally connected, as at 22, to the discs I2 of the drum ID. 'The flanges 2| have formed therein slots 23 which accommodate securing elements 24. The slots 23 permit swinging adjustment of the buckets 20 on the 5 pivots 22. The bottoms 25 of the buckets 20 are formed to provide pockets 26 which communicate with the ports l5 and I6 for receiving dust from the drum l0.

Pivotally mounted on the frame structure I m for swinging adjustment in. a vertical plane beneath the drum I0 is a chute 21. Rods 28 suspend the free end of the chute 21 beneath thedrum ID. The upper ends of the rods 28 are engageable selectively in openings 29 which are provided therefor in the frame members 3'fo'r adjusting the inclination of the chute 21.

It is thought that the operation of the machine will be readily apparent from a consideration of the foregoing. Briefly, the grain to be treated is placed in the hopper 5 and the dust to be mixed with said grain is placed in the drum Ill through the door II. The slide 6 is then opened to permit the desired volume of grain to flow by gravity from the hopper 5. This grain enters the buckets 20 and the drum I is turned by gravity in an obvious manner. This grain then drops into the inclined chute 21. As the drum I0 is thusrotated the dust therein flows through the communicating ports l5 and I6 and, during the ascent of the buckets 20, collects in the pockets 26. Then, during the descent of the buckets 20 this dust falls by gravity from the pockets 26 and is thoroughly mixed with the grain on the inclined chute'2'l. As hereinbefore stated, the flow of grain from the hopper 5 is regulated by the slide 6. By loosening the wing nuts l9 and rotating the ring I3 relative to the ring l4, thus shifting the ports l5 relative to the ports IS, the flow of dust from the drum l0 may be controlled as desired. By varying the inclination of the chute 21 the speed at which the grain will be discharged therefrom may also be regulated as desired. Thus, adjustments may be conveniently made to successfully meet substantially all conditions. By adjusting the buckets 20 on the pivots 22 the capacity of the pockets 26 may be increased or decreased.

'It is believed that the many advantages of a grain treating machine constructed in accordance with ,the present invention will be readily understood and although a preferred embodiment of-the device is as illustrated and described, his to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

1. A grain treating machine comprising a supporting structure, a hopper mounted on said supporting structure, a drum, for the reception of dust, rotatably mounted on the supporting structure beneath the hopper, said drum having peripheral ports therein for the discharge of the dust, and means on the drum engageable by the grain flowing from the hopper for rotating said 2. A grain treating machine comprising a supporting structure, a hopper mounted on said supporting structure, a drum, for the reception of dust, rotatably mounted on the supporting structure beneath the hopper, said drum having ports therein for the discharge of the dust therefrom, means mounted on the periphery of the drum and engageable by the grain flowing from the hopper for rotating said drum, and a chute mounted on the supporting structure beneath the drum for receivingand mixing the grain and the dust.

3. A grain treating machine comprising a supporting structure, a hopper, for the reception of grain, mounted on said supporting structure, a

drum, for the reception of dust; rotatably mounted on the supporting structure beneath the hopper, said drum having peripheral ports therein for the discharge of the dust therefrom, buckets mounted on the periphery of the drum and adapted to catch the grain from the hopper for rotating said drum, pockets in the buckets communicating with the ports for receiving the dust therefrom, and means for regulating the flow of the dust from the drum.-

4. A grain treating machine comprising a supporting structure, a hopper, for the reception of grain, mounted onsaid supporting structure, a drum rotatably mounted on the supporting structure beneath the hopper, said drum for the reception of dust and including a pair of spaced discs, relatively rotatable rings mounted on the ment on the periphery of the drum, said buckets including pockets communicating with the ports for the reception of the dust, means for securing the buckets in adjusted position on the drum, and means for discharging grain to be treated into the buckets for rotating the drum.
